1. Getting Started

1.1. About This Guide

This guide describes Layer 2 service and EVPN functionality provided by the Nokia family of routers and presents examples to configure and implement various protocols and services.

This guide is organized into functional chapters and provides concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.

The topics and commands described in this document apply to the:

  1. 7450 ESS
  2. 7750 SR
  3. 7950 XRS
  4. VSR

Table 1 lists the available chassis types for each SR OS router.

  2. 7450 ESS-7/12 running in standard mode (not mixed-mode)
  1. 7450 ESS-7/12 running in mixed-mode (not standard mode)
  2. 7750 SR-a4/a8
  3. 7750 SR-c4/c12
  4. 7750 SR-1e/2e/3e
  5. 7750 SR-7/12
  6. 7750 SR-12e
  1. 7950 XRS-16c
  2. 7950 XRS-20/40

For a list of unsupported features by platform and chassis, refer to the SR OS R16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA.

Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.

Note:

This guide generically covers Release 16.0.R1 content and may contain some content that will be released in later maintenance loads. Refer to SR OS R16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA, for information about features supported in each load of the Release 16.0.R1 software.

1.2. Layer 2 Services and EVPN Configuration Process

Table 2 lists the tasks related to configuring and implementing Layer 2 Services and EVPN functionality.

This guide is presented in an overall logical configuration flow. Each section describes a software area and provides CLI syntax and command usage to configure parameters for a functional area.
